| 摘 要： | 首先，我们描述了水珠和干粉末在驻波推动作（钢条和金属环）表面上的艺定分布实验，发现水珠将处于波腹而干粉末则位于波书．其次，我们从普遍的驻波解出发，分析了在驻波振动作表面上的水珠和干粉末的受力情况，从而指出水珠的稳定平衡位置在驻波的波腹而干粉末的稳定平衡位置在驻波的波节，这一结论与实验结果完全一致。最后，我们的结论可以应用于环形驻波马达的转子自校正问题。

| Abstract: | Firstly, we describe an experiment on the stable distribution of water drops and dry powders on the vibrator surface(steel bar or metal hoop)forming standing wave.It was found that the drops collected at the antinodes while the dry powders at nodal points. Secondly, we start from the general solution of standing waves to analyze the force state of the water drops and dry powders on the vibrator surface and conclude that the steady balance locations for water drops are antinodes while there for dry powders are nodes. This agrees with exparimantal results. Finally, we remark that our results may apply to rotor self-correction problem of hooptyPe standing wave motor. |
